Got a letter today for a vehicle inspection notice, says its for noise control.

Any idea to find out how i was seen in the first place ect.

The car is loud, says it has to be under 90db at 4800 revs. any way i can check at my own mechanic first at all?

Would be best bet to just switch over to stock exhaust for inspection? is there much involved, Im using the one it came from japan with.

does it say exhaust noise and emissions control systems? or just noise? DECCW always want to see that your standard emissions control systems are in place (exhaust, intake, bov, intercooler, charcoal canister).

do you have to take it to a certain place that they have listed? any chance of showing the form they sent you?

i recently had to go through the same thing.

k for deccw u need 2 have it quite and all emissions gear on, such as stock bov, stock side mount cooler, stock air box, stock turbo if u have an aftermaket one, stock computer, charcoal canister

I have been there and done it myself and got a few of mates cars ready for it is well

You did say R33 NA, right? That will half your problems right there - no BOV, intercooler or turbo to worry about!

Get another muffler fitted, get the exhaust shop to test it before you hand any money over (make sure you've let them know what you want when you leave it with them, obviously) and take it for the inspection or whatever they've asked you to do.

dont bother with the extra muffler. ive got a way to get it to pass. my exhaust went from 96db (completely stock exhaust) to 82db with my little 'mod'. PM me and i'll guide you through it or even give you my one.

also make sure you have a standard cat and DONT go to the guy in granville. ive heard lots of crappy stories about what he thinks a stock cat is. the guy in campbelltown actually knows what hes doing and isnt after your $.

Car is NA and the only mod is the Exhaust. its got a Cat, and a new muffler, still quite loud tho. Not testing for emissions, Just has to be under 90DB at 4800 RPM.

Yes i have a listed place their approved workshops. il gets some pics of the form up asap.

they dont check for those things mate, you can easily hide it. they dont take your exhaust apart to check.

the pics i sent you in the PM explain what to do. just dont tell them what you did.

you also need a STANDARD cat. it can not be aftermarket. the exhaust can be any brand you like as long as it passes the noise test.

thats just what they ask for when you do the inspection.

you can go to the inspection with whatever gear you want. but you will be sent a defective vehicle notice if it doesnt meet their requirements (all stock items fitted). but when you receive the defective vehicle notice you can go to the IM240 test and pass that with whatever gear you want fitted.

They have an "Anti Tempering" section to pass by the looks of it, A baffle in the joint sounds a bit dicey. care to explain?

Get a peice of metal, cut it out the same shape as the flange at the cat end of the catback. Then drill holes in the middle that mean you have effectively blocked half your exhaust. This means you have bad flow, hence bad power and bad flow in the form of a restriction which leads to big drops in noise :)

Very very cheap nasty way of solving the problem.

Thats my best bet at the moment, going in the the local exhaust shop for a noise test. $30. Will have a chat to him about the making up the metal piece behind the flange.

Cheers. il let you all know how i go.

Ive been DECC 3 times already for "noise" pollution and all 3 times have gone to that "granville guy" and passed. Its not difficult, trust me on this one.

lol why would you go through the trouble of fabricating pieces thats going to take you a couple of hours to make and fit when you can just go borrow a standard exhaust and slap the thing on in 30 mins. Much easier, simpler and a GUARANTEED pass. Its a N/A car after all.

    • Welcome to my 2004 Toyota Mark ii IR-V Fortuna (series 2) With a 1JZ-GTE powerplant under the bonnet (hood) it'll give me plenty of scope for power upgrades. For those who aren't familiar with imports, the 1JZ-GTE is a 2.5L 6 cylinder VVTi engine with a single turbocharger. This has the factory R154 5 speed gearbox, along with a aftermarket 2 way LSD differential (brand unknown). Under the arches are a set of CST Zero 1 alloys, 18x9 +30 225/40 up front and 18x9.5 +15 265/35 on the rear. The car was quite low in Japan and there's evidence of the wheels catching the rolled arches/fenders. The tyre's aren't great so I'm in two minds whether to replace both or just the tyres and put up with the wider wheels on the rear. The car still uses stock brakes with the addition of some braided hoses. The exterior is stock with the exception of a BN Sports front bumper and a replacement Fortuna grill  Moving to the interior, the steering wheel has been replaced with a dished MOMO steering wheel (which will get swapped for my Momo Tuner for the time being) Defi Link Gauges are mounted above the climate controls and on the A pillar, the Oil Temp,Oil Pressure,Water Temp and Boost gauges should help with spirited and track driving  The stock seats have been replaced with some retrimmed Recaro bucket seats. Being a larger build these are a little snug, unfortunately the orange isn't for me so I'll look into replacing these down the line. Other modifications include a twin plate clutch, Blitz intercooler, Evolve alloy radiator, a stainless exhaust with decat, HKS EVC-S boost controller and coil overs
    • Apologies for the long read My R34 GTT was up for sale at the beginning of spring due to a few repairs creeping up. The strut tops needed replacing, roof and bonnet (hood) painting (yay for 3 stage pearl) and the underside stripped and treated. I sold the car which allowed me to be in a much better place financially. Leading up to the sale I was already thinking about the replacement. In an ideal world it needed to be a good all-rounder. Something I can mess around with, modify, do track days, do the school run, go on long drives etc.  Options included but not limited to... Laurel C35, Evo 8/9, Civic FD2, Impreza Hawkeye, Aristo and even an Audi S4 Avant (I've already got the Mazda 6 wagon). But there was always one car at the top of the list The Toyota Mark ii JZX110 I found an advert on a Facebook group for an example in Japan, from a seller called Jon at Rising Sun Exports. A few messages back and forth and Jon calls me from Yokohama one morning (or afternoon in his case). He briefly explained the import process, the costs involved and a repeat of the advert. After much deliberation, the price was agreed and the sale was locked in. I've never imported a vehicle so I jumped into the unknown head first. The money transfer was completed through wise.com (fees apply), very easy to use and the money was with him within a day or two.  The car suspension was raised for the vessel and the car dropped off at the port. It was 7 weeks later when the bill of lading was received and the freight invoice sent to me, followed by the export certificate a couple of days after (both digital copies) In the mean time the port had been in contact. I needed an agent to deal with the NOVA (notification of vehicle arrival) along with the tax/duty invoice, this was £75.00. The port also had a fee of £100, I'm guessing to cover the cost of the 10 day 'free storage' and for moving the car off the boat etc. They need a copy of the vehicle invoice, freight invoice and export certificate to allow the vehicle to pass through customs. The vessel arrived on Tuesday 5th August, the tax/duty invoice was generated and sent over. This is generally tax 20% and duty 10% of the vehicle value. Although the invoice came in at a higher amount than I had calculated. Once HMRC had received the payment the vehicle could be released from customs. I thought once the tax/duty was paid you could collect at any point, that's not the case. Your agent will need to book a collection slot, I requested Thursday 7th which was accepted, with a 9:00am slot allocated. It was a 5:00am start from Norfolk heading to Southampton. We eventually found the compound, upon presenting the bill of lading and some ID they released the car (they drove it out of the compound to the front ready for us to load up). The email from the port stated each slot had a 10 minute window, which seemed abit farfetched but the staff said it's not a strict rule. We were there for approx. 30-40 mins in total. A week prior to collecting I contacted my garage and explained the situation, I was able to get an inspection slot that afternoon. For the registration, DVLA require the car to be insured, for this I used a company called Adrian Flux who can insure the vehicle using the VIN number. 
    • Hey guys, looking for these side skirts if anyone can help me out. 
    • Wife and I are still looking for a new home. One condition was a large enough garage for a full-size lift in one bay. Now if only we could find something... We've been looking for almost a year now.
    • Thanks everyone for the ideas! Sadly, ramps are a no go for me. With young kids at home, I do most of my work late at night while they're sleeping. Starting the car multiple times wouldn't be a great idea.  I'll go see one of those new long reach low profile jacks and take a couple measurements to see if they will fit.
